Did you guys pay the extra $40 to have the unit assembled and fit/leak tested?
Yes
Couple more questions if you don't mind......
How many times can/have you reused your butane?
Is the yield substantially more than with the tube method?
Do you grind the herb first?
Have you tried a second wash on the herb?
How long is the process from start to finish?
Do you use heat or ice method?
I know it depends on strain used but what's a single run producing on average?
I filled the butane tank and have been reusing that same batch, save for topping off due to leaving some 'tane behind for easier recovery.
I would say I get around 5-10% more return, depending on material used.
I never grind my herb, merely remove larger stems if need be.
I have ran material for a second time and gotten a negligible amount of lower quality oil. The machine is very efficient for a single-pass device.
From starting to pack the tube, to preparing to vac-purge the results, takes about 2 hours, maybe a bit less. Where it takes much longer this way than using an open blaster, I think the other benefits are worth the trade-off.
Yes to both, I use temps as high as 110*f and as low as -10*f to help facilitate movement of the solvent.
I'd say I'm averaging about 16%, with lows around 8% and my highest returns above 23%.
good stuff
